Possible pregnant

Hi I am 6 days late for my period I keep getting the odd cramps but nothing really. I am not showing any symptoms really apart from being extra tired the last week for no reason. I was spotting mid cycle and on the first day of my period I started to spot pinkie then it stopped and then only when I wipe I now have brown discharge it’s only a little bit when I wipe anyone no what it could be. My boyfriend thinks i could be pregnant as I have been very emotional crying for no reason, and I feel sick and be sick a lot at night not in the morning. I am scared to do a test anyone got any advice? Does anyone think I could be pregnant?
